Divided cities are generally linked with civil wars in which group identity is threatened. This type of war dominated the late twentieth century, leaving many cities vulnerable. According to J. Calame and E. Chalesworth(2009) in Divided Cities: Belfast, Beirut, Jerusalem, Mostar, and Nicosia, since World War II there has been a marked shift in global warfare trends from inter - to intrastate conflict: of 64 wars between 1945 and 1988, 59 were intrastate or “civil” wars, and about 80 percent of those who perished were killed by someone of their own nationality. Mostar can be added as one more case some years later. Because of the division these cities hypofunction spatially and socially. In the case of Mostar, Neretva River is used in the frame of the politics of division, providing mental and physical spaces of shame. More specifically, it forwards a surface common memory, as supposed effort of reconciliation of the past with scattered stones, calling them monuments, around the city, leaving the core of its identity, the river, as an abandoned area. In order for the city to start functioning social normally again, it’s necessary to be created a common space of history, which will produce common memories for the future generations. The thesis tries to give a new insight on how to deal with a landscape where ordinary pleasant memories replaced with memories of terror (Neretva), responding to the need of the city for a new memorial architecture. Even though, it addresses a specific area (Neretva), could be influence for many other cities which suffer from post-traumatic events, since it will propose a memorial, not as a spot but, as a system, taking into account the complexity of social, historical, religion, economical, morphological parameters. The new memorial scape in Mostar will not represent a reason for being sad but rather a way to look and hope for the future, becoming with the river a symbol of the city. It is designed as part of the history, being a powerful reminder of society and how citizens of Mostar should stand together in the face of the tragedy of the war. It redefines the relationships between the local community helping the future generations to understand a bit of their history as well. The memorial scape tries to become a part of the Mostar culture, being based on the powerful connection between man and nature. The idea is not only to create a space that stands as a symbol of memory but also to allow people the opportunity to relax and enjoy a new green space. It is just as important for the memorial scape to serve the collective memory as it was to have a high functionality level, providing residents of the area with a new space to enjoy the open outdoors.
